| Zusammenfassung: | A single-end-output class D amplifier handles a load, such as stereo headphones, without using an expensive part such as a crystal resonator or transformer. The class D amplifier is equipped with PWM (Pulse Width Modulation) circuits that perform pulse width modulation of an input signal and output two opposite-phase PWM outputs, PWM output buffers that amplify differential outputs of PWM circuits using a power supply voltage, and inductors that combine PWM outputs amplified by the PWM output buffers. |
